    Description

    Field of the invention



    [0001] The present invention relates to an assembly for a motor vehicle.

    [0002] In particular, the present invention relates to an assembly for a motor vehicle as defined in the preamble of claim 1.

    Background art



    [0003] It is known that electric scooters or motor vehicles are provided with electric motors accommodated within the wheel.

    [0004] Due to the arrangement of the electric motor within the wheel, it is often impossible to also arrange the disc of a disc brake connected to the wheel hub and it is just as frequently impossible to arrange the caliper body within the rim of the wheel, a rim which is almost completely or completely occupied by the electric motor.

    [0005] Accordingly, the actual solutions of a wheel associated with an electric motor assembly and brake are particularly cumbersome, especially in the axial direction or in the direction which is parallel to the rotation axis of the wheel itself.

    [0006] The connection of the disc brake to the wheel is feasible if the electric motor, which is accommodated in the wheel, has a rotor arranged externally to the stator, for example as described in document KR101219059. Other solutions are known from JP2011073528A, US2008053719A1.

    [0007] Indeed, here the brake disc may be connected to the rotor, which is arranged keyed onto an axis to which the fork and the suspension of the motor vehicle are connected, the suspension to which the brake caliper is in turn attached. The document JP 2011 0743528 discloses an assembly for a motor vehicle in accordance with the preamble of claim 1.

    [0008] If instead the use is provided of an electric motor having the rotor arranged inside the stator so as to form an electric motor cartridge which can be easily replaced inside the wheel and is capable of remaining clean of dirt and debris, and is also simple and quick to replace, here it is substantially impossible to also arrange the braking system within the rim.

    [0009] Thus, the need is strongly felt to position the disc brake in scooter wheels so as to ensure a small size, especially in axial direction.

    [0010] Indeed, wheel rims with a small diameter are often used on scooters and therefore it is fundamental to leave ample space in axial direction for a motor which, not being able to extend in radial direction, requires increased width to exert the desired torque.

    [0011] Moreover, the need is strongly felt to make braking systems for a scooter with electric traction which are simple and safe to install, and especially to service.

    Solution



    [0012] It is thus the object of the present invention to devise an electric motor assembly for a motor vehicle and brake capable of meeting the needs mentioned above and of solving the problems of the background art.

    [0013] These and other objects are achieved by means of an assembly according to claim 1. Certain advantageous embodiments are the object of the dependent claims.

    Drawings



    [0014] Further features and advantages of the electric motor assembly for a motor vehicle and brake according to the invention will appear in the description below of its preferred, non-limiting example embodiments, with reference to the accompanying drawings, in which:
    • figure 1 depicts an axonometric view of a portion of a fork of a scooter or motor vehicle connected to an electric motor fitted within a rim of a wheel;

    [0029] In accordance with one embodiment, said first half-caliper 12 is made in one piece with said motor casing 4 or said first-half-caliper 12 is alternatively made in one piece with said fork 11.

    [0030] In accordance with one embodiment, said motor casing 4 comprises a support plate 14 keyed onto said bearing 10. In accordance with one embodiment, said motor casing 4 further comprises a stator housing 15 attached circumferentially to said support plate 14.

In accordance with one embodiment, said stator housing 15 faces and is sealed to said rotor sealing flange 16 so as to provide an motor casing 4 which is substantially sealing with respect to the external ambient so as to limit the introduction of dust or debris into motor 2.

    [0033] Thereby, said motor, with the motor casing 4 and rotor 5 thereof, forms an motor cartridge 2 which can be interchanged without the need to disassemble rotor 5 and stator 3.

    [0034] In accordance with one embodiment, said rotor 5 comprises a rotor ring 19 with which permanent magnets 20 are associated, which are arranged facing said stator windings 17 and stator laminations 18.

    [0042] Due to the solutions described above, the axial volume may be reduced and, in addition to positioning an electric motor within a rim of a wheel, a caliper disc assembly and an arm of the suspension of the motor vehicle may be positioned axially side-by-side.

    [0043] Moreover, due to the solutions described above, the disc brake caliper may be integrated with the casing of the electric motor or the stator of the electric motor.
